Not every business requires sophisticated telecom services, such as SIP or MPLS. For some businesses, business phone service with DSL or Cable internet does the trick. If you called your local phone or cable company and were informed that DSL or cable internet were not available, there are a number of reasons that might be the case. To better understand the reasons and plan ahead when picking a location to operate your business, read ahead.
Distance from the Wire Center: DSL service from the phone company is distance sensitive – the further your location is from their wire center – the lower the bandwidths that are available. At some point, you can’t get the service period. Repeaters and amplifiers are used to increase the reach of DSL but distance is still the number one reason DSL might not be available in your area.
Load coils: Load coils are filters that block out any non-voice frequency. Load coils are necessary for voice communication, on a business phone line, to travel over longer distances. DSL cannot travel through load coil.
Pair Gain: Pair Gain is utilized to multiply the number of phone lines available in a given area. At the beginning of the internet, people used dialup. In the nineties, two phone lines to a home became commonplace. Also, small ISPs were popping up all over the place that required tens of business phone lines. At the same time, due to the higher cost of housing, the population was spreading out to areas under served by phone company networks. In an effort to meet the demand, the phone company used Pair Gain to increase the supply of phone lines. The existence of Pair Gain precludes DSL.
No DSLAM in the Wire Center: The phone company’s wire center is where your phone lines originate. A Digital Subscriber Line Access Multiplexor (DSLAM) is a device used to create DSL internet service. A DSLAM is an expensive piece of equipment. If a given area is not densely populated or there are few businesses willing to pay the higher cost of business DSL, the phone company that services the area will be less likely to install a DSLAM in its wire center.
Typically, if you can receive cable TV, you can receive cable based internet access. When cable was introduced, it was primarily a residential service; commercial zones were left off the network. So with cable, you either have access to it or you don’t. Cable companies will build out to a business, but require certain ROI minimums to be met. Typically, a business wanting cable will need to subscribe for a certain dollar amount of service for a particular number of months – or recruit neighboring businesses to subscribe as well, in order to fund the construction required.
At this point in time, internet, in one form or another, is universally available. T1, wireless and satellite based internet services fill in the DSL and cable’s coverage gaps. Because of the existence of these other technologies, the phone and cable companies might not find it profitable to resolve DSL and cable internet servicing issues. Businesses outside the reach of DSL and cable can still acquire internet access, they just might have to pay more or accept lower levels of performance. The best approach is to enlist the help of a telecom consultant to help your company navigate through all the possible options.
